1. Functional nursing has some advantages, which one is an EXCEPTION?

A. Psychological and sociological needs are emphasized.
B. Great control of work activities.
C. Most economical way of delivering nursing services.
D. Workers feel secure in dependent role

Correct answer: B

Rationale: Functional nursing is a task-oriented approach where each nurse is assigned specific duties, leading to efficient task completion but often resulting in a lack of holistic care. While functional nursing may provide great control over work activities and can be cost-effective due to specialization, it does not emphasize psychological and sociological needs, which is a significant disadvantage. Additionally, the dependent role that workers feel in functional nursing can lead to disempowerment and hinder professional growth and autonomy. Therefore, option A, 'Psychological and sociological needs are emphasized,' is the exception among the advantages of functional nursing.

2. What is the medical term for ingrown hair?

A. Folliculitis
B. Hirsutism
C. Pseudofolliculitis Barbae
D. Alopecia

Correct answer: C

Rationale: The correct answer is C: 'Pseudofolliculitis Barbae.' This term specifically refers to ingrown hairs commonly seen in the beard area. Folliculitis (A) is inflammation of the hair follicles, not necessarily due to ingrown hairs. Hirsutism (B) is excessive hair growth, unrelated to ingrown hairs. Alopecia (D) is hair loss, which is also not related to ingrown hairs. Therefore, 'Pseudofolliculitis Barbae' is the medical term specifically used to describe ingrown hairs in the beard area, making it the correct answer.

A. 12 milliliters
B. 24 milliliters
C. 60 milliliters
D. 120 milliliters

Correct answer: B

Rationale: First convert minutes to hours (1 hour * 60 minutes). Then, multiply the number of drops per minute (40 drops/minute) by the volume per drop (0.05 ml/drop) and by the conversion factor (60 minutes/hour) to find the total volume delivered: 40 drops/minute * 0.05 ml/drop * 60 minutes/hour = 24 milliliters.
